What are you guys using for HTML Newsletter software? I'd like something where I can see some stats, etc so I can show them to clients, etc.

Easy to use piece of software with good stats, etc.

I had been using PHPlist without any problem.

Its not just that PHPlist is free, its good too.

I have to say that 1-2-All is a sweet looking piece of software. I have used several others in the past few years and had recently started using MailChimp.com and CampaignMonitor.com to do client mailings. While 1-2-All does not have the complete set of features that these have, it comes pretty close. I am seriously thinking of buying it and running my own mailings again. The only benefit I can think of to stay with one of the services mentioned is that they have direct contact with the free email services like Hotmail, AOL, and Yahoo. My mail has a higher chance of getting in because of their contracts with these mail providers.

We use DadaMail, which is a very good mailing script.

I just came across MailChimp.com as I was looking for a good mail list program.
I like the fact that they give you very good stats on your list and that you don't have to pay a monthly fee. They even offer a free trail that is fully functional! They also have a wealth of information about creating your mailing lists, etc...
